A new study suggests that the more teenagers watch television, the more likely they are to develop depression (抑郁症) as young adults.

The researchers used a national long-term survey of healthy young teenagers of about 13—16 to find out the relationship between media(媒体) use and depression. They based their findings on more than 4000 young teenagers who were not depressed when the survey began in 1995.

As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio. Here was the result. The young people spent five and a half hours a day using media and more than 2 hours of that was spent watching TV.

Seven years later, in 2001, more than 7% of the young people had signs of depression. The average age at that time was 21. Brian Primack at the University of Pittsburgh medical school was the lead author of the new study. He says every extra hour of television meant an 8% increase in the chances of developing signs of depression.

The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio. But the study did find that young men were more likely than young women to develop depression given the same amount of media use.

Doctor Primack says the study did not find out if watching TV causes depression directly. But one possibility, he says, is that it may take time away from activities that could help prevent depression, like sports and social activities. It might also prevent a person from sleeping well, he says, and that could have an influence.

The study was just published in the Archives of General Psychiatry.

In December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Researchers from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, attend social services and to vote.

Two new studies suggest that modern running shoes could increase the risk of injuries（损伤）to runners.

One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were watched on a running machine. Sometimes they wore running shoes. Other times they ran barefoot（赤脚）.

Researchers from the University of Virginia and the University of Colorado did the study. They found that running shoes create more stress that could hurt knees, hips and ankle joints than running barefoot. They watched that the effect was even greater than the effect reported earlier for walking in high heels（高跟鞋）. The study appeared in an official scientific magazine.

The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University, Moi University in Kenya and the University of Glasgow. They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.

Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they feel relaxed when landing and avoid hitting their heel hard.

Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.

But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.

The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems. So they have tried to explain their findings on a Harvard Website.

1.Why do running shoes increase the risk of injuries to runners?

A new study finds that more than eighty percent of Internet users in the United States search of health information online.

Susannah Fox from the Pew Internet Project says doctors are still the main source of health information. But the study found that searching online is one of the leading ways that people look for a second opinion. He says, “People are sort of fact-checking what they have heard from a doctor. Our studies show that people are still very likely to turn to a health doctor when they need a diagnosis (诊断) or are planning a treatment.”

Forty-four percent of people are actually looking for doctors or other providers when they search for health information online.　 Two-thirds of Internet users look online for information about a certain disease or medical condition.

The Internet has also become an important source of spiritual support for people with health problems. Susannah Fox says one in five Internet users has gone online to find other people who have the same condition.　

A disease is considered uncommon if it affects(侵袭) fewer than 200,000 people worldwide. The rise of social networking has made it easier for people with uncommon diseases to connect with each other and feel less alone. Social networking is also changing the way some doctors and patients communicate with each other.

Dr. Jeff　 Livingston operates a medical center for women in Irving, Texas. His office uses password-protected software to share information with patients. He says the software has increased efficiency(效率)， reduced costs and improved relations with patients. It has just changed the way we do health care. His medical centre also has a Facebook page, a Myspace page and a Twitter feed.

It sounds almost too good to be true, but a new study on sleeping brains suggests that listening to languages while you sleep can actually help you to learn them.

For the study, researchers played recordings of foreign words and their translations to students who were enjoying slow-wave sleep. During this period, a person has little knowledge of their environment. To make sure that the results were not compromised by foreign language words that students may have had some connection with at some point in their waking lives, researchers made up the words which cannot be found in the foreign language at all.

When the students woke up, they were presented with the made-up words again without their translations. The students were then asked to imagine whether this made-up word showed an object that was either smaller or larger. This vague (not very clear) way of testing their understanding of the words is a method that is supposed to make use of the unconscious (无意识的) memory.

The researchers were surprised to find out that the students were able to correctly group the words in this way. And their accuracy rate (精确度) was 10 percent higher than accidental chance. That’s not a rate high enough to help them get ability of communicating with others in a foreign language, but it is enough to suggest that the brain is still taking in information on some level, even during sleep.

It has been long believed that sleep is important for memory, but before this research its role in memory was thought to relate only to the preservation (保存) and organization of memories that students got during wakefulness. This is the first time that memory formation ( 形 成 ) has been shown to be active during sleep. In other words, our brains are listening to the world, and learning about it, even when we are unconscious of what is happening around us.

The next step for researchers will be to see whether new information can be learned quicker during wakefulness if it was already presented during sleep. If so, it could forever change how we train our brains to learn new things. Sleep learning might become a widespread practice.

1.The word “compromised” in Paragraph 2 probably means “　　 ”.

A.influenced B.depended C.finished D.studied

2.What were the students asked to do in the study?

A.Group the words they heard by size. B.Repeat the words they heard in the sleep.

C.Imagine the meaning of the made-up words. D.Make up a word to describe “large” or “small”.

3.The researchers probably agree that　　 .

A.sleep is necessary for a good memory B.memory formation goes on during sleep

C.listening during sleep is good for our health D.learning languages in sleep has better effects

4.What will be the researchers’ next plan?

A.To train people how to learn during sleep.

B.To dig out the reason for unconscious learning.

C.To explain the benefits of unconscious memory.

D.To study the effect of sleep learning on conscious learning.
